ELECTRIC TlME-lNDlCATlNG SYSTEM.

SPECIFICATION forming part of Letters Patent No. 350,430, dated October 5, 1886.

Application filed May 6, 1890.

To all whom it may concern:

Be it known that 1, CHARLES A. HUssEY, of New York, in the county of New York and State of New York, have invented a certain new and useful Improvement in Electric Timelndicating Systems, of which the following is a specification.

I will describe an electric time-indicating system embodying my improvement, and then point out the various features in claims.

In the accompanying drawings, Figure 1 is a diagram illustrating an electric time-indieating system embodying my improvement. All the parts ofthis system which are located in the office whence the system is controlled I have surrounded by a line, adjacent to which I have marked the word Office. Fig.2 of the drawings is a side view of certain parts arranged in the office. Fig. 3 is a side view of certain other parts arranged in the office.

Fig. i is a side view of certain partsof an elec tric or secondary clock.

Similar letters of reference designate corresponding parts in all the figures.

A designates the shaft for a sweep secondhand in a primary mechanical clock or regulator. This clock or regulator may be of any suitable kind and operated by a weight. The shaft A, it must be understood, makes one complete rotation during each minute. On the shaft A is ZtlfiXGCl a wheel, A, having a notch, a, in its periphery. Adjacent to the wheel A a wheel, A, is arranged in the primary clock or regulator. As shown, the wheel A isjournaled loosely in a swinging arm, A,

which is pivotally connected to a red, A located in the primary clock or regulator. The wheel A rests upon the periphery of the wheel A. XVhenever the notch c in the periphery of the wheel A. comes opposite the wheel A the latter dropsinto it. The arm A of course descends with the wheel A when the latter drops into the notch.

A designates a rod in the primary clock or regulator, which has at the lower end an offset or shoulder, a, extending under the swinging arm A. As shown, the arm A has a projection, a", opposite the offset or shoulder (t of the rod A. When the swinging arm A descends on the dropping of the wheel A into the notch a of the wheel A, the projection a Serial X0. 201,400. (No model.)

makes contact with the offset or shoulder a of the red A.

The rods A A and the swinging arm A are to be made of metal. The other parts which I have mentioned may or may not be of metal.

The rods A" A are to be insulated from each other. This may be done by supporting them in a frame of insulating material, ror by interposing pieces of insulating material between them and the frame, if the latter is not made of insulating material. The rod A has connected to it a wire, A which extends to one pole of an electric battery, A. From the other pole of the battery A a wire, A, eX- tends. A wire, A extends from the rod A \Vhenever theswinging arm A" descends in the manner which I have explained and its projection a makes contact with offset or shoulder a of the red A", the wires A and A are inelectrical communication. This electrical communication will be only momentary, owing to the fact that the notch a of the wheel, A is of very slight extent. The notch is p referably so short in the direction of the periphery of the wheel A that the contact of the projection u? of the swinging arm A with the offset or shoulder a of the rod A will exist only for two seconds during each rotation of the sweep second-shaft A. The wire A is connected to a binding post, A, with which one end of the wire of an electro-magnet, A, is connected. The wire A is connected to a binding-post, A, with which the other end of the wire of the electromagnet A is connected.

It will be understood, in view of the foregoing explanation, that whenever the swinging arm A is allowed to drop, so that its prej ection a will make contact with the offset or shoulder a of the rod A the electric-magnet A will be momentarily energized from the battery A The electro-magnet A is mounted upon one pole of a permanent horseshoe-magnet, A, whose other pole has pivoted to it a swinging armature, A, for the electromagnet A. This armature is of coursea polarized armatnre. The armature A, as shown, extends above the electro-magnet, and when occupy ing its normal position extends over the space between the poles. the armature toward one pole of the electromagnet. The armature is attracted toward A spring, 05, tends to pull against the contact-piece b the other pole of the electro-magnet when the electro-magnet is energized. The armature A vibrates between two metal contact-pieces, a" a (shown as consisting of screws,) so as to be adjustable. Normally, the armature is held against the contact-piece a by the spring a. When the electro-magnet is energized it is vibrated over against the contact-piece a momentarily.

B designates an electro-magnet, which is similar to the electro-magnet A, is, like it, mounted upon one pole of a permanent horseshoe-magnet, 13, whose other pole has pivoted to it a laterally-vibrating armature, B, impelled in one direction by a spring, b, and attracted in the other direction by the electro magnet B. The armature B vibrates between two metal contactpieces. (Shown as consisting of adjustable screws 1) b Normally, the spring b holds the-armature B" against the contact-piece b". \Vhen the electro-magnet B attracts the armature, it swings the latter Line-wires O G extend from the armatures A B and out of the office to places where electric clocks are located.

D designates a battery for sending currents of electricity along the line-wires O 0". A wire, D, extends from one pole of the battery D to a binding-post, d, which is connected by a wire, D", to' the contact-piece I). The binding-post d is also connected by awire, D, with a binding-post, d, which is connected by a wire, D", with the c0ntaet-piece a. A wire, D extends from the other pole of the battery Dto a binding-post, (1 which is connected by a wire, D, with the contactpiece (r and by a wire, D, with a binding-post, d, that is connected by a wire, D", with the contact-piece If. It will be seen that as the armature A B are normally in contact with the contactpieces a b, respectively, they are normally in electric communication with one pole of the battery D. When the electro-magnet A? is energized and it vibrates the armature A against the contact-piece a it shifts the armature into electrical communication with the other pole of the battery D. Thereupon an electric current passes from the battery D along the line-wires G 0 If the electro-magnet B is energized,the armature B will be shifted over into communication with the other pole of the battery D,and

then, assuming that the armature A occupies its normal position,an electric current will pass over the line-wires O O. This time the electric current will flow in the reverse direction to thatin which it flows when the armature A is shifted by the electro-magnet A I will remark here, in order to conduce to a clear understanding of my improvement, that the electric current is made to flow from the battery D in one direction over the linewires 0 O by the electro-magnet A and the mechanism operating in conjunction therewith to cause the electric or secondary clocks which I employ to record hours and minutes, and that the electric current is made to flow from this battery in the reverse direction over the line-wires O (J by the electro-magnet B and the mechanism controlling the latter to cause the operation of the calendar mechanism of the electric clocks whereby days of the month are recorded. f

I will now describe the mechanism whereby the operation of the electro-magnet B is controlled. Awire, B, extends from the wire A to a binding-post,which is connected with one end of the wire of the electro-magnet B. The other end of the wire of the electro-magnet is connected to a binding-post,with which a wire, B", is also connected. The wire B is connected toa rod, B in the primary mechanical clock or regulator. This rod B is to be made of metal, and has at the lower end an offset or shout der, 1). B isaswinging arm, made of metal and having a projection, b, opposite the offset or shoulder b" of the rod B The swinging arm B has journals supported by bearings consisting of screws or pins Zr, fitted to metal rods '13 B arranged in the primary clock or regulator. The rod B is connected by a wire, B", with the rod A", and hence is in electric communication with the wire A which leads to one pole of the battery A The-rods B B are insulated from each other and from the rods A A Whenever the swinging arm B is allowed to descend, so that its projection b will'make contact with the offset orshoulder b of the rod B an electric circuit will be completed from the battery A along the wire A to the wire B, thence through the rod B to the swinging arm B", thence over the latter to the rod B and thence along the wire B to one end of the wire of the electro-magnet B. An electric current will then flow from the battery A to the wire of the electro magnet B, because the other end of the wire of this electromagnet is always connected to the battery A through the wire A. \Vhen the electromagnet B is thus energized, its armature B will be shifted over to the contact-piece If, and an electric circuit will then pass from the bat tery D over the line-wires O C".

I will now describe the manner in which the swinging arm B is operated. B is a rod supported in the frame of the primary clock or regulator. Under it is arranged a rotary shaft, B, on which is affixed a wheel, B, having aficam surface, I)", on one side. The lower end of the rod B is provided with an offset, b", that projects into the path of the cam-surface b" of the wheel B, and is adapted to extend under a projection, b, with which the swinging arm B is provided. The lower portion of the rod B is resilient. \Vhen the cam-surface I) of the wheel B comes opposite the rod B", the latter will be sprung or moved aside; Its offset b" will then be moved from under the swinging arm B and the-latter will descend, so that its projection b will, make contact with the offset 2) of the rod B As soon as the cam-surface b" has passed by the rod B", the latter will be ready to assume its original position and support the .having sixty teeth.

swinging arm B again. It cannot, however, assume its normal position until the swinging arm has been raised to its normal position. The swinging arm 13 will be raised to its normal position by a cam or eccentric, B, on the sweep second-shaft A. As the shaft A rotates rapidly, the swinging arm B" will only be left in contact with the rod 13 momentarily. The shaft 13 is provided with a wheel, B, which has twenty-four teeth. On the sweep second shaft A a tubular minute-hand shaft, 13", is arranged. This minnte-hand shaft makes a rotation once every hour, and is provided with a wheel, 13 having a single tooth that engages once in each rotation with the wheel B and moves the latter a short distance. A spring-actuated tooth, B", which engages with the wheel 13, insures the latter being moved a distance equal to the distance between two adjacent teeth each time the wheel 13 engages with it, It also causes the wheel 13" to move quickly each time it moves. The wheel B starts each movement of the wheel 3 and the spring-actuated tooth B completes the move ment quickly. This springactuatcd tooth 13" also prevents the wheel B from moving improperly. .It will be understood from the description l have given that the wheel B, the shaft B", and cam-whecl B rotate once each twentyfonr hours, or, in other words, once a day. The circuit is therefore closed to the elect ro-magnet B but once a day. As the elec tro-magnets A and B have only to vibrate their armainrcs in one direction, it is not cs sential that they should have polarized armatu res or the permanent magnets comhi ned with them. if not provided with polarized armatures, they would of course have to be turned over into a proper position to move thearmatures in the desired direction.

E designates the electric clocks or secondary clocks of the timetelegraph. They are arranged in multiple-arc circuits. Each has a shaft, 0, which is provided with a wheel, 0,

V This wheel 0 has combined with it a pawl-lever, c", that has affixed to it an artnatu re, (1", for an elcctro-magnet, c. The shaft 0 is a minute-shaft. In other words, it makes a complete rotation once every hour. The minute-hand of the clock is affixed to this shaft. Gearing is combined with this shaft to transmit motion to the hour-hand shaft. The hour-hand shaft I have not shown, as it has nothing to do with myinvention. Every time an electric circuit is completed through the electro magnet A the latter will shift its armature A and cause an electric current to tlow from the battery 1) to the electro'magnet c. The latter will thus be energized and will vibrate the lever 0". The pawls of the lever c will then move the wheel 0 and shaft 0 the distance of one tooth on said wheel. This will occur once every minute. The minutehand will be moved in'this way once every minute for the distance of a minute over the dial of the clock.

I will now describe the manner in which the electric current flows to each electro magnet 0*. One end of the wire of the electro magnet e is connected with the line-wire O. The other end of the wire of this electromagnet is connected with a metal contact-piece, c. This contact-piece is shown as consisting of a screw. Opposite it is a similar contact piece, 0'. Between the two contact-pieces e 0 extends the armature c" of an clectro-magnet, 0 the ends of whose wires are connected with theline-wires C 0 The electro magnet c is mounted upon one pole of a permanent magnet, c. The armature c" of the electromagnet c is pivotally connected to the other pole of the permanent magnet c. It is therefore a polarized armature. Springs c normally hold the armature c midway between the contact-pieces c c. The armature c is connected by a wire, 0, with the line-wire C Each time the sweep second-shaft A in its rotation permits of a contact between the swinging arm A and the rod A, and the electromagnet A" is in consequence thereof energized so as to shift its armature against the contactpiece a, and an clectricenrrent flows from the battery 1) to the line-wires C 0-, the electric magnets c of the electric or secondary clocks will be energized. Thereupon the armatures e of such clcctro-magnets c will be shifted over to the contact-pieces e". Electricity will then flow from theline-wires through the wires of the electro-magnets c and the wheels 6 will be shifted one tooth, and the minute-hands carried thereby move a distance to indicate one minute on the dials. Each electric or secondary clock is provided with a tubular shaft, 0, which tits upon the shaft 0, and is provided with a wheel, 0, having thirty-one teeth. Combined with this wheel 0' is a pawl-lever, c. On the pawl-lever c" is the armature e of an electroanagnet, c. One end ofthe wire of the electro-magnet c is connected to con tact-piece e, the other end of such wire be ing connected to the line-wire Each time one rotation of the shaft B of the primary clock or regulator causes a contact of the swinging arm B with the rod 3", which will be once every day, as before explained, the clectro magnet B will be energized, its armature B will be shifted over against the contact-piece. If, and an electric current from the battery 1) will be caused to pass over the linewires 0' C in the reverse direction to that in which it passes when the electromagnet A is energized, as before explained. Then the electro-niagnets c of the electric or secondary clocks will be energized in such manner as to shift their armature 0'' over against the contact-pieces c, whereupon electricity will pass from the linewires O G" to the electromagnets 0" of the electric or secondary clocks. \Vhen these electro-magnets c are thus encrgized, which will be once every day, the pawllevers 0 will be vibrated so as to more the wheels 0 one tooth. Calendanhands on the shafts 0 will then move a distance to indicate the date of another day upon the dials of the electric or secondary clocks. Obviously the primary clock or regulator must be so organ izcd that the swinging arm A cannot make contact with the rod A at the same time that c 0 Stops 6' consisting, preferably, of ad- [0 justable screws, are employed to limit the movements of the pawl-levers.

I will now describe a means whereby the electric or secondary clocks may be set from the office where the primary clock or regulator is located. G G designate keys consisting severally of a metal frame, 9, and a metal lever, g,journaled to the frameg and capable of being rocked up and down. The lever g is provided on its under side with a contactpiece. The frame 9 is provided beneath .the lever with a contact-piece, g, which is insulated from the frame. A wire, G extends from the rod B of the primary clock or regulator, and is connected to the'levers g of the keys G .G*. A wire, G, extends from the binding-post, in which the wire 13* is secured to the contact-piece 9 of the key G, and a wire, G extendsfrom the binding post A,in which the wire A" is secured to the contact-piece g of the key G By depressing the lever gof the key Ga communication with the battery A will be made from one pole along the wire A to the wire B, from the latter to the wire G thence to the frame of the key G; thence to the lover of the key; thence to the contactp iece 1/ of the key and along the wire G to the wire of the electromagnet B. As the other pole of the battery is always in communica tion with the wire of the electromagnet, the circuit is then complete. Each time the key G is thus opera ed the armature B will be shifted over to the contact-piece I), whereupon an electric current from the battery D will energize the eleetro-magnets e of the secondary or electric clocks, so thatthey will shift their armatures 0 over against the contactpieces 6'', and will then energize the electromagnets 6 so as to cause the latter to shift the pawl levers c, and through them the wheels 0 and calendar-hands. In this way the calendar-hands of the electric or secondary clocks may be set. By depressing the lever g of the key G a communication with the battery A will be made from one pole along the wire A to the wire B"; thence to the wire G, to the frame g of the key; thence to the lever g of the key; thence to the contact-piece of the key, from the latter along the wire G to one end of the wire of the electro-magnet A. The other end ofthe wire of the electro-niagnet A being in communication with the battery A through the wire A", the circuit is complete. Whenever the key G is thus operated,the electro-magn'et A will shift its armature A over against the contact-piece a and .a current of electricity will pass from the battery D over the line-wires O O" to the electromagnet e of the electric or secondary clocks. The armatures e of these electromagnets will thereupon be shifted against the contact-pieces c and the electric current will be caused to flow to the wires of the electromagnets 6 Then the electro-magnets 6' will operate the pawl-levers c and cause the latter to shift the wheels 6 of the shafts e, carrying the minute hands. Obviously, a galvanometer, V, may be combined with the linewires 0' or (J in the office to indicate their electrical conditions.

' I will now describe means whereby theelectro-motive force will be sustained at points distant from the oflice where the battery D is located. I designates a supplemental battery connected at one pole by a wire, I, with a binding-post, i, and at the other pole by a wire, 1, with a binding-post, t. The binding-post t is connected with a binding post, i bya wire, I, and the binding-post t" is ,connected by awire,.I",'with a binding-post,

t. The binding-posts it t" i are connected with contact-pieces t" i i i" (Shown as consisting of adjustable screws.) J J" designate electio-magnets mounted on poles of permanent horseshoe magnets J J", and having armatures J J pivotally connected to other poles of these permanent magnets. These armatures are consequently polarized armatures. They are moved over to the contactpieces 1" t by springsj, and are shifted by the electro-magnets over to the contact-pieces i 17. One end of the wire of the electro -magnet J is connected to the wire 0. The other end of the wire of this electro-mague't is connected to one end of the wire of the electro-magnet J The other end of the wire of the electro-magnet J is connected to the line-wire C". The armature J ofthe electro-magnet J is connected bya wire, J to the line-wire C. The armature J of the electro-inagnet J is con nected to the line-wire O by a wire, J. The eleetro-magnets J J and their armatures J J are so constituted that when an electric current flows to the wires of these electromagnets from the line-wires O C in one direction the armature J? will be shifted and the armature J will not, and so that when an electric current flows to the wires of the electromag: nets in the other direction the armature J will be shifted and the armature J will not. There may be any desirable number of the batteries and their appurtenances. When the battery D is connected with the line-wires by the-shifting of the armature A through the electro-magnet A by reason of the contact of the swinging arm A with the rod A each battery I will be connected with the line-wires, so that electricity will flow therefrom in the same direction as from the battery D,owing to the shifting of the proper armatures J or J to connect the batteries I in that manner with the line-wires.

I do not here claim the features of the primary clock or regulator or the features of the electric or secondary clocks shown and described in this application, except in combination with other things, as hereinafter particularly specified. I intend to the applications for Letters Patent covering the novel features of my primary clock or regulator and the electric or secondary clocks.

I have filed, on June 18, 1886, an application for patent numbered 205,562, for an improvement in primary clocks for electric timeindicating systems, in which I claim special features ol' construction in said primary clock.

I have liled an application for Letters Patent foran improvement in electric line-indi eating systems numbered 205,564, June 18, 1886. In this application I show a primary clock or regulator having two circuit-closing mechanisms, line-wires adapted to form two circuits, and electric or secondary clocks having two electromagnetic mechanisms for operating different parts. In this application I also show electro-magnets having their armatures connected with certain of the line-wires, a main battery for supplying electricity to the line-wires connected. at one pole with contactpieces,against which the said armature will be vibrated when the electro-magnets are energized, and connected at the other pole to one of the line-wires, which is not connected with the armatures, and local circuit-wires connected to the coils or wires of the electromagnets and extending to CllClllil ClOSlDgl116Chanism in the primary clock or regulator. In this application I also show a supplemental battery and electromagnetic mechanism for connecting the supplemental battery with either of the two circuits, as circumstances may require. I do not in this application lay claim, broadly, to the electric time-indicating system therein claimed.

I do not in the present application lay claim, broadly, to the electric timeindicating system therein claimed.
